4 is really enough (fighter, two damage dealers and a healer), 6 is already a clutter, means that developers need to have 50% more enemies in every battle making battles longer and screen more cluttered.
Maybe 5 would be a compromise, but 6 party members is an outdated game mechanic already.
LOL let's say it to Owlcat, Inxile and Obsidian (ok, 5 in POE2, but it was 6 in POE1 5 years ago)
